Current Electricity

  1. The resistances in the two arms of the meter bridge are 5Ω and RΩ, respectively. When the resistance R is shunted with an equal resistance, the new balance point is at 1.6 l1. The resistance ‘R’ is :​​

    1. 10Ω ​
    2. ​15Ω ​
    3. 20Ω ​
    4. 25Ω
Correct Option: B

​This is a balanced wheatstone bridge condition,

⇒​R = 15 Ω
